COILING LEAD PIPE.

SPECIFICATION forming part of Letters Patent No. 278,696, dated June 5,1883,

' Application filed February 28,1883. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN FARRELL, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Manufacture of Lead Pipe and I do hereby declare thefollowing to be a full, clear, and exact description thereof.

My invention relates to apparatus designed to prevent the flattening ordistortion of lead pipe produced by winding it upon a reel into bundlesor coils for subsequent handling or sale. This winding or coiling isdone directly as the pipe leaves the machine by which it is formed. Thepipe passes first over a large drum, usually of five or six feet indiameter, and

thence to the coiling-drum, which is much smaller in size, being usuallyabout eighteen inches in diameter. The passage over the large drum doesnot injiu'e the pipe, because of the large diameter of the drum. Theinjury is done by the reel, which is necessarily small, in order to givethe coil the proper size for handling and sale. I have discovered that,if the original shape of the pipe is preserved at the point where itencounters and begins to conform to the shape of the reel, it may besafely coiled without further danger of flattening or distortion. Tothis end, therefore, I have devised my present invention, which I willnow illustrate by reference to the accompanying drawings, in whichFigure l is a side elevation, partly in section, of my improvedapparatus; and Figs. 2 and 3 are detail views.

The drawings illustrate parts of a form of press for making lead pipe,in which a is the presscylinder, having a cylindrical lead-chamber, a.This cylinder rests upon a supporting-block b, which has apassage, b,for a corerod, 0, and a concave socket, b forthe support of the core.The core a has a rod, 0, which lies in the passage 7), and a rounded orconvex shoulder, c", which rests in the concave socket If. The core iscentered by means of adj Listing-screws N, which extend in from oppositesides of the supporting-block b. The plunger (1 has a central bore, (1,for the pas: sage of the core 0 and of the pipe as it is forced out ofthe machine. In thelower end of the plunger is a die-socket, (Z for thereception wheel 71, heretofore spoken of, and in any "suitable positionat the side of the same is the small drum or reel The pipe, afterleaving the bore d of the plunger, is led around the drum h to the reel2 upon which it is coiled into the bundles or coils before -mentioned.As stated, the effect of such coiling is to cause a flattening ordistortion of the pipe, whereby it is reduced from around to a flattenedor elliptical form in cross-section. This distortion is especiallyinjurious to the larger and lighter grades of lead pipe, involves awaste I of money and material, and causes more or less trouble inplumbing operations. As before stated, my invention is designed to pre;vent this distortion.

To any suitable point on the frame m of the machine I fasten a wire ropeor chain, a, which is of sufficient length to extend to the point uponthe reel 43, where the pipe encounters and begins to bend around thereel. Herel fasten to the rope or chain, by means of eyes R, an invertedsegmental trough, k, the circle of which is concentric to that of thepipe and of a size to fit snugly around it. The pipe is led over thedrum h to the reel 2', where it is passed through the trough k, and thenis coiled around the reel. The internal diameter of the trough beingjust sufficient for the passage of the pipe, there is no room for thelatter to flatten out or enlarge laterally when passing throughthe-trough, the curved sides k of whichpreserve the shape of the pipe.As

before stated, the subsequent winding of the pipe up on the reeli pastthe point at which the trough 0 ends does not produce any injuriouseffect upon the pipe, so that I secure a coil of pipe which is perfectlyround in cross-section, and obviate the difficulty of flattening,heretofore experienced. I do not limit myself to making round pipe inthis way, but claim the use of the invention for any form which it isdesirable to give the pipe.

I do not limit myself to the use of an inverted trough or guide, butclaim any form of external device which, encircling or placed at thesides of the pipe, will prevent or oppose the increaseof the diameter ofthe pipe in a direction parallel to the face of the coiling reel ordrum. If desired, such external device may be supported in a frame andcapable of being brought down into the proper position It is not neces-.

ox er the upper side of the reel. sary therefore that it be attached tothe leadpipe machine, as shown in the drawings; nor is it necessary thatthe pipe should pass directly from the machine to the reel, as it may bedrawn out upon the floor, and subsequently reeled. This makes nodifference with my improvement, as it is used and applied only when thereeling operation takes place.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

1. The combination, with a press for forming lead pipe and a reel ordrmn for coiling the same, of a trough or guide operating on theexterior of the pipe at or about the point where it is bent in reelingor coiling, substantially as and for the purposes described.

2. The combination, with a reel ordrum for coiling lead pipe, of atrough or guide operating on the exterior of the pipe at or about thepoint where it is bent in reeling or coiling, substantially as and forthe purposes described.

3. The method of preserving the shape of lead pipe during the operationof coiling, consisting. in passing it between external surfaces at orabout the point where it is bent to conform to the curve of the reel toprevent its extension in a direction at right angles to the plane inwhich it is bent, substantially as and for the purposes described.

I11 testimony whereof I have hereunto set my hand this 23d day ofFebruary, A. D. 1883.

JOHN FARRELL.
